As of early 2026, Delaware remains one of the few U.S. states with no billionaire residents officially listed on major wealth trackers like Forbes. While Delaware is famous for being a corporate haven—home to over 60% of Fortune 500 companies due to its favorable tax laws and Chancery Court—the individuals who own these companies typically reside in neighboring states like Pennsylvania, New York, or Maryland. The wealthiest individuals actually living in Delaware are often part of the Du Pont family, whose collective wealth is massive, but as individuals, their net worths generally fall into the "hundreds of millions" category rather than the "billions" bracket. In 2026, Delaware continues to share this "zero billionaire" status with a small group of states including Alaska, North Dakota, and West Virginia. For those seeking "Billionaire Row" in 2026, you are much more likely to find it in California (124 billionaires) or New York (93 billionaires).
